Images are widely used in web pages. However, most web images can only be viewed passively. Currently, it remains inconvenient for users to collect and save web images for further editing. The positioning of a certain image in web pages with a large number of images, such as the image search results, is also troublesome and time-wasting, especially for mobile devices with small screens. In this paper,...
This paper presents a three-dimensional intersymbol interference (ISI) equalization algorithm employing turbo equalization for detection of 3D binary images in holographic storage systems. The algorithm scans the 3D received image along rows, columns, and files, and iteratively exchanges weighted soft information between maximum a posteriori (MAP) detectors for each scan direction until convergence...
Image quality evaluation is becoming essential in many image processing problems. This paper proposes a new image quality evaluation approach based on decision fusion method of canonical correlation analysis (CCA). By exploring several diverse visual models, we constructed a comprehensive quality metric which can deal with complicated image distortion problem with increasing accuracy and robustness...
Anisotropic diffusion can remove noise to some extent in image processing. However the contradiction between diffusion and preservation still exists. In this paper, a new nonlinear diffusion model for image noise removal and feature preservation is presented. This model treats inhomogeneity region and image feature adaptively by discontinuity measure and local gradient information. A well balance...
